The powder listed was G-O, 3F, in a 43" test barrel and had 15,000 CUP, 2354 FPS, and 2212 muzzle energy. The two powders they used back then was Curtis- Harvey and Gearhart - Owen. It sure isn't a load I would have used. C-H quite making BP in 1931. Ned Roberts rated Curtis and Harvey's "Diamond Grain" BP as the absolute "very best" powder, "as it burns moist, easily wipes clean after each shot, doesn't burn-on at the breech" and was consistent lot-to lot.

Ned H. Roberts (1866 Goffstown, N.H. -- 1948), was an American hunter, competition target shooter, gun writer & editor, ballistician and firearms experimenter. Roberts was a prolific contributor to sporting publications, including Outdoor Life, Outers, Arms and the Man (later renamed as
American Rifleman,
[1] and to Hunting and Fishing magazine, for which latter publication he served as Firearms Editor. His work on cartridge design in collaboration with
Adolph Otto Niedner,
Franklin Weston Mann,
Townsend Whelen, and F.J. Sage led to a commercialized version of his own original .25-caliber wildcat cartridge introduced by Remington in 1934 and named the
.257 Roberts. And I always thought GOEX was the best. Little did I know.
